Question

Answer really quickly please

Answer 1

a. 65:195

b. A

Explanation:

for part a:

1:3 means there are 1+3=4 parts

so 260/4=65

so the 1 is 65 and the 3 is 3(65)=195 so

a. 65:195

for part a.

3:5 is equal to 1:n

so divide 3:5 by 3 on both side so

3/3 : 5/3 =

1:5/3

b. A

Answer 2

see explanation

Explanation:

(a) Add the parts of the ratio, 1 + 3 = 4 parts

Divide 260 by 4 to find the value of one part of the ratio.

260 ÷ 4 = 65 ← value of 1 part of the ratio, thus

3 parts = 3 × 65 = 195

260 in the ratio 1 : 3 = 65 : 195

(b)

Given

3 : 5 ← divide both parts of the ratio by 3

`(3)/(3)` :
`(5)/(3)` = 1 :
`(5)/(3)` → A
