let x = decrease 80- 80 x = 70 80(1-x) = 70 1-x =70/80 x = 1-70/80 = 0.125 = 12.5%
56/80 x 100 = 70 Therefore, 56 is 70 percent of 80.

7/8 x 80 = 70
2 x 5 x 7 = 70
let x = decrease 80- 80 x = 70 80(1-x) = 70 1-x =70/80 x = 1-70/80 = 0.125 = 12.5%
56/80 x 100 = 70 Therefore, 56 is 70 percent of 80.
80 - 70% = 80 x (1 - (70/100)) = 24

70 x 80 = 5600
it is 21?
The product of 70 and 40 = 70 x 40 = 2800.

80 x 70 = 5600 - 35 = 5565
80% of 70 is 560.8 x 70 = 56so 20% off100 - 80 = 20
70 can be expressed as a product of its prime factors as 2 × 5 × 7.
