Gia spends 2\5 of her money on a shirt and 4\9 of her remaining money on shoes. What fraction of her money is left?

1 answer:

5 0

2/5 + 4/9 is equivalent to 18/45 + 20/45 which equals 38/45.

45/45 - 38/45 = 7/45 of her money is remaining
Someone correct me please, if I'm incorrect.

3 Fred is making a fruit salad. The ratio

marusya05 [52]

Answer: 24 cups.

Step-by-step explanation:

Let be "x" the amount of cups of peaches that Fred will need to make 60 cups of fruit salad.

According to the information given in the exercise, you know that the ratio of cups of peaches to cups of cherries is the one shown below:

$2:3$

Which can also be written as a fraction:

$\frac{2}{3}$

Then, if he uses 2 cups of peaches and 3 cups of cherries, he will get 5 cups of fruit salad.

Knowing the above, you can set up the following proportion:

$\frac{2}{5}=\frac{x}{60}$

Now you must solve for "x" in order to find its value. This is:

$(60)(\frac{2}{5})=x\\\\x=24$
