Convert the following fractions to decim 30/20

Answers

For this case we must convert the following fraction into a decimal number:

$\frac {30} {20} =$

If we divide numerator and denominator by 2 we have:

$\frac {15} {10} =$

If we divide numerator and denominator by 5 we have:

$\frac {3} {2} = 1.5$

Thus, the fraction is equivalent to 1.5 (decimal form)

Answer:

$\frac {30} {20} = 1.5$

Answer:

30/20= 3/2= 1.5 is the decimal

Determine which of these does NOT illustrate two quantities that combine to make 0. A) Jane collects 12 seashells and then loses 12. Eliminate B) Sharon lost 8 pounds and then gained 10 pounds. C) A business's profit if its income is equal to its expenses. D) Frank wins five dollars and pays back a $5 debt to a friend.

Answers

Answer:

Option B is the correct answer.

Step-by-step explanation:

A. Jane collects 12 seashells and then loses 12. This combines to become 0. as first Jane gets 12 shells and then loses same 12 totaling to 0.

B. Sharon lost 8 pounds and then gained 10 pounds. This does not combine to become 0. As Sharon lost 8 pounds then gained 10 making it a total of $10-8=2$ pounds.

C. A business's profit if its income is equal to its expenses. When the income and expense are equal, the profit is 0. Like you earned $100 and you spent $100, so you have basically 0.

D. Frank wins five dollars and pays back a $5 debt to a friend. This also combines to get 0. Frank gets $5 and then loses it by paying debt, so he is left with 0.

Therefore, option B is the only correct answer.
