Question

Sasha solved a division problem by subtracting and keeping track as shown. Identify the problem that was solved. 492 - 450 15 x 30 42 -30- - 30 15 x 2 12 32 R12​

Answer 1

Sasha solved the division problem of 492 ÷ 15 by using repeated subtraction, arriving at a quotient of 32 with a remainder of 12.

Step-by-step explanation:

The student is working on a division problem by using repeated subtraction. The process they are using is division by subtraction, which involves repeatedly subtracting the divisor from the dividend and keeping track of how many times this subtraction occurs before the dividend is reduced to a value less than the divisor. Based on the student's work:

• They start by subtracting 450 from 492, which leaves 42.
• Next, they note that 15 multiplied by 30 equals 450. This implies that they were able to subtract 30 units of 15 from the original number.
• The remainder is 42, from which they can further subtract two more units of 15 (30 in total), leaving a remainder of 12.

So, the division problem solved was 492 divided by 15. The quotient is 32 and the remainder is 12, which can be represented as 492 ÷ 15 = 32 R12.
