20 points!!! Solve Each Proportion-Round to the nearest tenth *<br> Your answer

KatRina [158]

Answer:

x = 3.6

B. {7.88}

Step-by-step explanation:

$\frac{6}{x}= \frac{10}{6}$

x · 10 = 6 · 6

10x = 36

10x ÷ 10 = 36 ÷ 10

x = 3.6

$\frac{9}{8} =\frac{x}{7}$

8 · x = 9 · 7

8x = 63

8x ÷ 8 = 63 ÷ 8

$x=7\frac{7}{8}$ or x = 7.875

7.875 rounded to the nearest tenth is 7.88.

Rachel has a bag of fruit that has a mass of 50 hectograms. Rachel converts this mass to centigrams. Her work is shown below.

Alinara [238K]

Answer:

She should have multiplied by 10,000

Step-by-step explanation:

Given table:

$\begin{array}{| c | c |}\cline{1-2} \sf kilo & 1,000 \\\cline{1-2} \sf hecto & 100 \\\cline{1-2} \sf deka & 10 \\\cline{1-2} \sf unit & 1 \\\cline{1-2} \sf deci & 0.1 \\\cline{1-2} \sf centi & 0.01 \\\cline{1-2} \sf milli & 0.001 \\\cline{1-2}\end{array}$

To find the conversion rate:

$\sf \dfrac{hecto}{centi}=\dfrac{100}{0.01}=10000$

Therefore, 1 hectogram = 10,000 centigrams

So when converting hectograms to centigrams, multiply the mass by 10,000.

⇒ 50 hg × 10,000 = 500,000 centigrams

Rachel's error was that she should have multiplied by 10,000.
