Question

Andres uses mental mrh and his knowledge of multiplication to solve 167 ÷ 8. Andre knows that 8 x 20=160. Andre then subtracts 167 - 160=7. How can Andre use this information to find the quotient?

Answer 1

by adding 15 plus 10

Answer 2

Andre can use this information because 7 cannot go into 8 evenly, and 8 can go into 167 20 times, because 20 x 8 = 160

Therefore, 167/8 is 20 remainder 7
