What equation results when you cross - multiply 17/d = 51/21
nekit [7.7K]

Answer:

 51d=357\\\\d=\frac{357}{51} \\\\d=7

Step-by-step explanation:

A proportion is an equation that defines that two ratios are equal.  When the terms of a proportion are cross multiplied, the cross products are equal.  Cross multiplication is the multiplication of the numerator of the first ratio by the denominator of the second ratio and the multiplication of the denominator of the first ratio by the numerator of the second ratio:

\frac{a}{b} =\frac{c}{d} \rightarrow ad=bc

Therefore:

\frac{17}{d} =\frac{51}{21} \\\\17*21=d*51\\\\357=51d\\\\Solving\hspace{3} for\hspace{3} d\\\\d=\frac{357}{51} \\\\d=7

Estelle has 6 liters of juice. If she pours 0.25 liters into each glass, how many glasses of juice will she make?
aleksley [76]

Answer:

24 glasses

Step-by-step explanation:

We are given that

Estelle has juice=6 liters

She pours juice in one glass=0.25 L

We have to find the number of glasses of juice made by her.

Using unitary method

0.25 L juice pour in 1 glass

1 L juice pour in 1/0.25 glasses

6 liters  juice pour in glasses=\frac{1}{0.25}\times 6

6 liters  juice pour in 24 glasses

Hence, she will make 24 glasses of juice.
