It is not necessary to have a common denominator when you multiply two fractions

<h3>How to determine the true statement?</h3>

The statement is about the relationship between the denominator of fractions when they are multiplied

Take for instance, we have the following fractions

a/b and x/y

In the above fractions, we have

Numerator = a and x

Denominator = b and y

Where b and y do not have the same value

When they are multiplied, we have

Product = ax/by

The denominators do not have the same value

And we were able to calculate the product

This means that the fraction denominator do not have to be common

Answer:

tan30°=7/x

$\frac{1}{ \sqrt{3} } = \frac{7}{x } \\ x = 7 \sqrt{3}$

cos30°=x/y

$\frac{ \sqrt{3} }{2} = \frac{7 \sqrt{3} }{y} \\ \\ 7 \sqrt{3} \times 2 = \sqrt{3} \times y \\ \frac{7 \sqrt{3 } \times 2}{ \sqrt{3} } = y \\7 \times 2 = y \\ 14 = y$

tell me if it's wrong.

If 36^12-m=6^2m what is m

vagabundo [1.1K]

Answer:

m= 72/37

Step-by-step explanation:

36 x 2 - m = 6^2m

Multiply the numbers:

72 - m = 6^2m - 72

Subtract 72 from both sides:

-m - 36m = 36m - 72 - 36m

Simplify:

37m= -72

Divide both sides by 37:

-37m/-37 = -72/-37

Simplify:

72/37

A factory uses 1/6 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 1/2 of a barrel of raisins.

lord [1]

Answer:

The factory made 3 batches of granola bars.

Step-by-step explanation:

Given that:

1/6 barrel of raisins is used in each batch of granola bars.

1/6 barrel = 1 batch

1/2 barrel = x batches

As the relationship is proportional,

1/6 : 1 :: 1/2 : x

Product of mean = Product of extreme

$\frac{1}{6}x=\frac{1}{2}$

Multiplying both sides by 6

$6*\frac{1}{6}x=\frac{1}{2}*6\\x=3$

Hence,

The factory made 3 batches of granola bars.
