25% of what equals 7:= 7 / 25= 7 / 0.25= 28 (25% of 28 = 7)
percent means out of 100 → 25% of 7/8 = 25/100 × 7/8 = (25×7)/(100×8) = 175/800 = (7×25)/(32×25) = 7/38 It would have been prudent to simplify the 25% before the multiplication: 25% of 7/8 = 25/100 × 7/8 = (1×25)/(4×25) × 7/8 = 1/4 × 7/8 = (1×7)/(4×8) = 7/32 But then again, it is expected that students should recognise 25% as ¼
7/25 = 7 ÷ 25 = 0.28 or 28%
y*7+25=165 y*7+25-25 = 165-25 y*7+ 0 =140 y*7/7 = 140/7 y=20
GM(7, 25) = sqrt(7*25) = 13.23 approx.
25 : 7 25/7 25 to 7
7 over 25 is the same as 7 divided by 25:7/25 = 7 ÷ 25 = 0.28

6/7 - 6/25 = 6*(1/7 - 1/25) = 6*(25-7)/(7*25) = 6*18/(7*25) = 108/175
