mezya [45]

Answer:

a. $\frac{70}{100}$

b. 0.7

c. 0.7=70%= $\frac{70}{100}$

Step-by-step explanation:

70% of 100 received an A, that is 70/100 times 100 equal to 70

$\frac{70}{100}*100=70$

a. 70% = $\frac{70}{100}$

b. $\frac{70}{100}$ = 0.7

Notice that 70/100 is equal to 7/10 which is 0.7

c. 0.7=70%= $\frac{70}{100}$

What is the greatest common factors of 120 and 6

horrorfan [7]

If we want to know the greatest common factor, we should ask: is one of the numbers divisible by the other? if yes, then the smaller number will be the answer!

let's try:

$\frac{120}{6} = \frac{60}{3} =20$

so, yes!
6 is the greatest common factor of the two:)

Evaluate a+b when a=5/6 and b=3 1/4

NemiM [27]

Answer:

4 1/12

Step-by-step explanation:

a = 5/6 b = 3 1/4 = 13/4

To add 5/6 + 13/4, we have to make the denominators the same:

20/24 + 78/24 = 98/24
To make it back to a mixed fraction:

4 2/24
4 1/12
