3/8 to 7/8 find the percent of change and is it decrease or increase

mote1985 [20]

Answer:133.33%

Step-by-step explanation:

For given change in fractions from $\frac{3}{8}$ to $\frac{7}{8}$

The initial fraction= $\frac{3}{8}$

New fraction= $\frac{7}{8}$

Change in fractions= New fraction-Initial fraction

$=\frac{7}{8}-\frac{3}{8}\\\\=\frac{7-3}{8}\\\\=\frac{4}{8}\\=\frac{1}{2}$

As change in fraction is positive thus it is an increase.

$\text{Percent of increase=}\frac{\text{increase in fraction}}{\text{initial fraction}}\times100\\\\=\frac{\frac{1}{2}}{\frac{3}{8}}\times100\\\\=\frac{1}{2}\times\frac{8}{3}\times100\\\\=\frac{400}{3}=133.33\%$

5. 40 = }(9x + 30) + 2

Anvisha [2.4K]

Answer:

x=-16

Step-by-step explanation:

We are given with the equation

$40=-\frac{1}{3} \times (9x+30)+2$

We are asked to solve it for x.

Distributing $\frac{1}{3}$ over bracket and simplifying

$40=-(\frac{9x}{3}+\frac{30}{3})+2$

$40=-(3x+10)+2$

$40=-3x-10+2$

$40=-3x-8$

Adding 8 on both sides

$48=-3x$

Dividing both sides by -3

$x=-16$
