IF you meant 75 percent of 20 - the answer is 15 !
75 /0.2 = 375
15 is 75% of 20
For example: 20% of 75Two methods:20 ÷ 100 × 75 = 15.20 × 75 = 15
3 is the hcf
You recognise that 20% is one-fifth so you multiply 75 by 5...
GCF(36, 75) = 3 so the answer is 1 and 3
75 50 + 20 = 5
3 and 15/20
The lowest number that both 15 and 25 go into is 75. 15 goes into 75 5 times, and 25 goes into 75 three times.
20. Method: call the unknown number n. From the problem statement, 3n + 15 = 75, or 3n = 75 -15 = 60 and n = 60/3 = 20.
1 and 5
