Evaluate

Mathematics
1 answer:
Montano1993 [528]3 years ago
3 0

Step-by-step explanation:

Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,

\frac{x}{y} * \frac{a}{b }= \frac{x*a}{y*b}

Addition and subtraction requires that we find a common demoninator.

For example,

\frac{6}{4} + \frac{4}{3}

The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.

\frac{6}{4}*\frac{3}{3} + \frac{4}{3} \frac{4}{4} = \frac{18}{12}+\frac{16}{12}

Then we add the numerators

\frac{18+16}{12} = \frac{32}{12}

Then we should reduce.

\frac{16}{6} = \frac{8}{3}

Division is a little trickier because we have to flip-flop the second term and then multiply. For example: \frac{1}{10} \div \frac{5}{6} \rightarrow \frac{1}{10} * \frac{6}{5} = \frac{6}{50}

PLEASE HELPPPPPP<br> The perimeter is 50 ft and the length is 15 ft.<br> What's the width?
SVEN [57.7K]

Answer:

10

Step-by-step explanation:

I assume it's a rectangle, therefore:

P = 50

a = 15 ft

b = ?

P = 2a + 2b

50 = 2 * 15 + 2b

50 = 30 + 2b

2b = 50 - 30

2b = 20

b = 10
