ANSWER:
$3 : $8
The ratio of Beth's savings to Carmen's savings is $3 : $8.
Explanation:
The problem is asking for the ratio of Beth's savings to Carmen's savings as displayed below.
Beth's savings : Carmen's savings
We will now establish the valuea given in the problem relevant to the above ratio and substitute it into the ratio.
Beth's savings = $30
Carmen's savings = $80
THEREFORE:
Beth's savings : Carmen's savings
$30 : $80
From this, we will ensure that the ratio is simplified fully by obtaining the highest common factor ( HCF ) of both the numbers in the ratio and dividing them by their HCF.
HCF = 10
THEREFORE:
$30 : $80
$30 ÷ 10 : $80 ÷ 10
$3 : $8
