Question

Increase 18 by a half

Answer 1

27

Explanation:

increasing by 1 half is like dividing. 4 increased by one half would be 6, because half of four is 2, and you add that on to four. increasing 18 by half, divide 18 by 2, that = 9 then add 9 onto 18. the answer is 27

Answer 2

36

Explanation:

if we were decreasing it would be 9 but if we are increasing it, it would be 36

just multiply by 2 or divide by 2
