Jennifer makes 1.7 liters of lemonade. If she pours 3 tenths of the lemonade in a glass, how many liters of lemonade are in the
Akimi4 [234]

Answer:

0.51 liters in the glass

Step-by-step explanation:

Given

Litres = 1.7L

Pour= \frac{3}{10}th

Required

Determine how many liters in the glass

To do this, we simply multiply the fraction poured by the total.

So, we have:

Poured = \frac{3}{10} * 1.7

Poured = \frac{3* 1.7}{10}

Poured = \frac{5.1}{10}

Poured = 0.51

<em>There will be 0.51 liters in the glass</em>

katovenus [111]
You figure out the amount of chocolate doughnuts sold by multiplying 2/3 by 7 1/4

first you change 7 1/4 to an improper fraction:
7 1/4= 29/4
now multiply 2/3×29/4 by multiplying the two numerators then putting that over the two denominators multiplied: (2×29)/(3×4)=58/12
now simplify:58/12=4 10/12= 4 5/6

the answer is Stanley's doughnut shop sold
4 5/6 trays of chocolate doughnuts
