Answer:
15?
Step-by-step explanation:
15% of 40
Of = Multiplication
15% Multiply by 40
Set up a equation
15/100= x/140
Cross Multiply
15* 140= 100*x
2100= 100x
Divide both sides by 100x
2100/100x= 100x/100x
X= 21
Answer:
The GCF of 27 and 72 is 9
Step-by-step explanation:
prime factorization of 27 is 3*3*3
