5 8ths 7/8 x 5/7 = 35/56 = 5/8
There are eight 8ths in a whole one.Therefore: 8 x 7 = 56 eighths in 7 whole ones.
7/8 x 5 is 4 3/8
7 x 8 = 56 7 / 8 = 0.875 Seven Eigths = 0.875
29/5 x 7 = 203/5 = 40 and 3/5
-4x - 7 = 16 -4x = 16 + 7 -4x = 23 x = -23/4 x = -5.75 Check: -4(-5.74) - 7 = 16 23 - 7 = 16 16 = 16
Yes, because: x+7 = 23 x = 23-7 x = 16
Not an even multiple. 2 x 7 = 14 (22/7) x 7 = 16 3 x 7 = 21
7 x 16 = 112
48 = 24 x 3 = 16 x 3 224 = 25 x 7 = 24 x 2 x 7 = 16 x 7 hcf(48,224) = 16
2 x 7 x pi x 16 or 224pi
Set up the prolem as x + 9 = 16 (with x representing the unknown number) and solve: x + 9 = 16 (then subtract 9 from each side of the equation to solve for x) x = 7 Prove the answer by substiting 7 for x: x + 9 = 16 7 + 9 = 16 16 = 16
