Answer:
413x6=345467
Step-by-step explanation:
Let's convert one of these numbers:
1 foot = 12 inches
9 feet were 9*12=108 inches
so the ratio would be 42: 108
or we can simplify it: divide by 2:
21:54
divide by 3:
7:18
A ratio always stays the same no matter the unit or currency, so it doesn't matter which unit we convert it to.
To solve this problem, we must figure out what percent of the total spending was spent on mommy and baby exercise programs. To figure this out, we should divide how much was spent on the mommy and baby exercise by the total amount spent on the district activities.
$1430/$5720 = 0.25
This is a percentage, or a portion out of 100, which means we must multiply this decimal by 100 to find its equivalent percentage.
0.25 * 100 = 25
Therefore, your answer is 25% of the total spending was spent on mommy and baby exercise programs.
Hope this helps!
