I need the answers for 1 a-d pleas

DaniilM [7]

We want to find a fraction that is between

$\frac{1}{4}\:and\:\frac{1}{2}$

There are several ways to go about this.

There are also infinitely many fractions that can be found between the given fractions.

Let us go for the one in the middle of the two fractions.

So we add the two fractions and divide by 2.

a) $\frac{\frac{1}{4} +\frac{1}{2} }{2}$

Find LCM for the numerator

$\frac{\frac{1+2}{4}}{2}$

Simplify:

$\frac{\frac{3}{4}}{2}$

$\frac{\frac{3}{2}}{2}$

$\frac{3}{8}}$

b) $\frac{\frac{1}{3} +\frac{3}{4} }{2}=\frac{13}{24}$

c) $\frac{\frac{1}{2} +\frac{3}{4} }{2}=\frac{5}{8}$

d) $\frac{\frac{3}{5} +\frac{7}{8} }{2}=\frac{59}{80}$

Find the ratio of the area of triangle XBY to the area of triangle ABC for the given measurements, if BY = 3, YC = 2

Mazyrski [523]

Answer:

The ratio of the area of triangle XBY to the area of triangle ABC is $\frac{9}{25}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

In this problem

Triangles XBY and ABC are similar, because the corresponding internal angles are congruent

see the attached figure to better understand the problem

step 1

Find the scale factor

Let

z-------> the scale factor

$z=\frac{BY}{BC}$
