IF you meant 75 percent of 20 - the answer is 15 !
75 /0.2 = 375
The number that goes into both 75 and 100 is their greatest common divisor (GCD). The GCD of 75 and 100 is 25, as it is the largest number that can evenly divide both. Therefore, 25 is the number that goes into both 75 and 100. Other common divisors include 1 and 5.
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
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.
3 and 15/20
20. Method: call the unknown number n. From the problem statement, 3n + 15 = 75, or 3n = 75 -15 = 60 and n = 60/3 = 20.
