1. setecientos dos x doscientos seis = ____
setecientos dos x doscientos seis is (702 x 206 = 144,612). The first answer starts with 200 which is not correct. The third answer starts with 300. That, too, is not correct. The last answer starts with 900. Again, that is not correct. The second answer (b) is 144,612. It is the correct spelling and correct form.
2. ochocientos uno x cien = ____
ochocientos uno x cien is (801 x 100 = 80,100). The first answer is 801,100. That is not correct. The second answer is 8,100,000. That is not correct. The last answer is 81. That too is not correct. The third answer is 80,100. It is spelled correctly and is in the correct form.
3. cuatrocientos once mil trescientos x novecientos diez = ____
cuatrocientos once mil trescientos x novecientos diez is 411,300 x 910 = 374,283,000). The answer is in the millions not billions so the third answer can be eliminated. The first answer begins with 600 and the second answer begins with 700. Neither of these is correct. The last answer is 374,283,000. It is spelled correctly and in the correct form.
4. seiscientos cincuenta x doscientos y trece = ____
To find the correct answer to this one you need to know the correct spelling. seiscientos cincuenta x doscientos y trece is (650 x 213 = 138,450). The 'y' is not used after the hundreds so the first answer is not correct as it has a 'y' after cuatrocientos. The second answer has a 'y' after ciento. Again, this is not correct. Remember, when the number is 100 through 199, the word ciento is used. It does not have an 's' at the end of the word. The third answer has improperly place un before the hundred and an 's' at the end of the word. The last answer is 138,450 and it is spelled correctly and it is in the correct form.
5. diez millones x diez = ____
diez millones x diez is (10,000,000 x 10 = 100,000,000). One hundred is cien. When you get to 101, a hundred becomes ciento. Therefore, the second answer is not correct as you do not have over 100 (i.e., 101 plus). The third answer improperly put un before cien. The last answer is for a billion which is not the correct answer. The first answer is the number for 100,000,000. It is the correct spelling and form.
6. ochenta y tres mil setenta y sies x trescientos diez y nueve = ____
ochenta y tres mil setenta y seis x trescientos diez y nueve is (83,076 x 319 = 26,702,214). The answer begins with 26. The first answer begins with 46. The third answer begins with 36 and the last answer begins with 56. Neither of these is correct. The second answer is 26,702,214. It is the correct spelling, form and answer.
7. quinientos treinta mil cuatrocientos x cinco = ____
quinientos treinta mil cuatrocientos x cinco is (530,400 x 5 = 2,652,000). To find the correct answer here you need to know the correct spelling and form. The first answer has misspelled the word for 600. The second answer is missing the word for thousand. The last answer has used the word for million twice. The third answer is 2,652,000. It is correctly spelled and it is the correct form.
8. cuarenta y uno x noventa y nueve = ____
cuarenta y uno x noventa y nueve is (41 x 99 = 4,059). The first answer is 3,029 and is not correct. The second answer is 7,039. It, too, is not correct. The third answer is 6,049 which is not correct. The last answer is 4,059 and it is the correct spelling and form.
