Question

A) Divide 260 in the ratio 1:3

b) The ratio 3:5 can be written in the form 1:n
Choose n from the following:
A. 5
B. 3
C. 1
D. 5

Answer 1

To divide 260 in the ratio 1:3, the first part would be 65 and the second part would be 195. The correct answer for the ratio 3:5 in the form 1:n is A. 5.

Step-by-step explanation:

To divide 260 in the ratio 1:3, we need to divide the total value into two parts based on the ratio given. To find the first part, we can use the formula:

First part = (Given ratio / Sum of the ratios) x Total value

First part = (1 / (1+3)) x 260 = 65

To find the second part, we subtract the first part from the total value:

Second part = Total value - First part = 260 - 65 = 195

Therefore, the two parts divided in the ratio 1:3 are 65 and 195, respectively.

For the second question, if the ratio 3:5 can be written in the form 1:n, then n would represent the number that corresponds to the 5 in the ratio. In this case, n is equal to 5 since it is part of the ratio 3:5. Therefore, the correct answer is A. 5.
