Chen completed the division problem below.

B. He multiplied the dividend by 100 instead of 10.

Step-by-step explanation:

Chen had to divide by . To make it easier to divide, he thought of multiplying both the dividend and the divisor by 10.

Chen multiplied the divisor by 10 but mistakenly multiplied the dividend by 100 instead of 10.

So his whole division problem was changed.

Therefore, the correct answer option is B. He multiplied the dividend by 100 instead of 10.

option B

He multiply the dividend by 100 instead of 10

Step-by-step explanation:

Given that,

divisor  = 0.9

dividend = 1.926

Chen decided to multiply each by 10 to get

divisor  = 0.9 x 10 = 9

dividend = 1.926 x 10 = 19.26

but unfortunately he multiply the dividend by 100

As,

1.926 x 100 = 192.6

So,

Chen's error was that he multiply the dividend by 100 instead of 10.

so, converting firstly the mixed fractions to improper fractions and then "adding".
