Find the value of n.

1.) 3/5 = n/35

2.) 90 : 54 = n : 3​


Sagot :

1) 3/5 = 21/35

35÷5=7

7×3=21

2) 90 : 54 = 1.8 : 3

90÷3=30

54÷30=1.8

1.) 3/5 = n/35

Divide 35 to 5

35 ÷ 5 = 7

Now we have 7, multiply it by 3

7 × 3 = 21

Final Answer:

n = 21

2.) 90 : 54 = n : 3

Turn the ratio into fractions

90 n

---- = ----

54 3

Divide

5 n

-- = --

3 3

Therefore, the answer is 5
