Answer:

D, 0.19

Step-by-step explanation:

So first you add up all the candies

you’ll get 79 pieces of candy

So 4 pieces of green candy

So we can just subtract 4 from 79 you’ll get 75 pieces

It still works becuase we know that 4 pieces gone are green so the other candies still have the same amount

Now there are 14 red pieces

So 14/75

Now simplify that and you’ll Get

0.18666666

Now round that, 0.19

write and solve a real- world problem involving the multiplication of a fraction and a whole number whose product is between 10

Tomtit [17]

Answer:

Real word Problem:- Jean is working in a pizza shop. She has 60 kg of flour. She has used one-fifth of it for making pizzas. How much flour she used for making pizzas?

Solution:- Quantity of flour she has= 60 kg

The quantity she used in making pizzas= $\frac{1}{5}\ of\ 60$

$=\frac{1}{5}\times60=12\ kg$

hence, she used 12 kg of flour for making pizzas.

Here the multiplication of a fraction and a whole number $=\frac{1}{5}\times60$ and its answer is between 10 and 15, since 10<12<15.
