Operations with fractions Please help !!!!! questions attached
Bogdan [553]

Answer:

1) 23/20

2) 14/5

3) 47/14

4)27/56

5) 10/7

6) 23/14

Step-by-step explanation:

We will apply the Least Common Multiple (LCM). because, each exercise has fractions without a common a denominator

\frac{3}{4} +\frac{2}{5} = \frac{15+8}{20} =\frac{23}{20}\\\\1 +\frac{9}{5} = \frac{5+9}{5} =\frac{14}{5}\\\\\frac{13}{7} +\frac{3}{2} = \frac{26+21}{14} =\frac{47}{14}\\\\\frac{5}{8} -\frac{1}{7} = \frac{35-8}{56} =\frac{27}{56}\\\\1 +\frac{3}{7} = \frac{7+3}{7} =\frac{10}{7}\\\\\frac{1}{7} +\frac{3}{2} = \frac{2+21}{14} =\frac{23}{14}

Anit [1.1K]

Answer:

The slope of WX and WY

Step-by-step explanation:

For us to have a rectangle, the angles at the edges equal 90

What this mean is that the width and the length are at 90 degrees

Hence, we can say that they are perpendicular to one another

Thus, we can calculate the slopes of both to drive home our point

Hence, by calculating the slopes of WX and WY, We can proof that we have a rectangle
