Question

problem using proportion)two sums of money care in the ratio 2:5the larger is $400.what is the smaller amount

Answer 1

160

Explanation:

2:5. we know that part of 5 is 400,

2/5 = ?/400

to make 5 equal to 400 as a denominator we must divice 400 by 5, that would make 80

2/1 = ?/80

Now we know that 1 portion is 80, then 2 portion would make 160

160

160 is the smaller amount.
