Decide whether each expression or fraction shows another way to write 3 Choose True or False for each expression or fraction. 3+ True False 15+ True 0 False 19 5 True False 7 5 를 O True O False ] 55+ 8 + 8 + + True 0 False

Answer 1

Answer:

Explanation:

Given the below mixed fraction;

$3\frac{4}{5}$

We can also express it as an improper fraction by multiplying the whole number by the denominator and adding the result to the numerator. We'll have;

$3\frac{4}{5}=\frac{19}{5}$

Let's go ahead and simplify each of the given expressions or fractions in order to decide which of them is the same as the above fraction.

1. For the 1st expression;

$\begin{gathered} 3+\frac{4}{5}=\frac{15+4}{5}=\frac{19}{5} \\ \end{gathered}$

From the above, we can see that the given expression is the same as our above fraction, so we'll choose ''True''

2. For the 2nd expression;

$\frac{15}{5}+\frac{4}{5}=\frac{15+4}{5}=\frac{19}{5}$

From the above, we can also see that the given expression is the same as our above fraction, so we'll choose ''True''

3. The fraction 19/5 is the same as the improper fraction we had above, so we'll choose ''True''

4. The fraction 3 4/5 or 19/5 can not be reduced to 7/5, so we'll choose "False" here

5. For the 5th expression;

$\frac{5}{5}+\frac{5}{5}+\frac{5}{5}+\frac{4}{5}=1+1+1+\frac{4}{5}=3+\frac{4}{5}=\frac{15+4}{5}=\frac{19}{5}$

From the above, we can also see that the given expression is the same as our above fraction, so we'll choose ''True''
