Kofi and Ella each have the same amount of money to spend on food shopping. Kofi spends 3/4 of his money and Ella spends 63% of
12345 [234]

Answer:

Kofi spent the most money.

Step-by-step explanation:

We have been given that Kofi and Ella each have the same amount of money to spend on food shopping. Kofi spends 3/4 of his money and Ella spends 63% of her money.

Let us convert 3/4 into percent.

\text{3/4 as a percent}=\frac{3}{4}\times 100\%

\text{3/4 as a percent}=0.75\times 100\%

\text{3/4 as a percent}=75\%  

We can see that \frac{3}{4} is equal to 75%.

Since both have the same amount of money, so 75% will be greater than 63% of same amount. Therefore, Kofi spent the most money.
