A. x/70 = 50/100 B. x/50 = 70/100 C. 50/70 = x/100 D. 70/x = 50/100 My answers: 4/7 as a percent. Round to the nearest tenth of a percent
= 0.57142 = 57.142% = 57.1% C .709 as a percent 70.9% B 81.25% of 21 = about 16 A 48% of 23.95 = about 12.00 A 15% of $58.50 = about 5.8 + 2.9 = 8.7 = about 9 B 50 is 12.5? 12.5/50 = 25/100 = 25% B 50 is 6.25% of what number 50 = 0.625 times X So x = 50/0.625 = 80 B 50% of 70% = 35 So the proportion would x/70 = 50/100 A
