6.RP.3A

Mathematical Equivalence

ON

Answer explanation

3.63 is the dividend & 0.6 is the divisor. The divisor can not be a decimal, so you would move the decimal one place to the right to make the divisor 6. If you move the divisor's decimal one place to the right you need to do the same to the dividend, so the dividend would become 36.3
