Question

for problems 7 - 10, circle true or false.

1. $\frac{8}{12}\overset{?}{>}\frac{8}{12}$ true or false
2. $\frac{50}{25}\overset{?}{=}\frac{12}{6}$ true or false
3. $2.2>2.09$ true or false
4. $8.15 = 8+\frac{1}{5}+\frac{10}{100}$ true or false

Explanation:

Problem 7:

Step1: Compare numerators

When denominators are the same ($12$), compare numerators. $8>8$ is false.

Problem 8:

Step1: Simplify the fraction

Simplify $\frac{50}{25}$ and $\frac{12}{6}$. $\frac{50}{25} = 2$, $\frac{12}{6}=2$. So $2 = 2$.

Problem 9:

Step1: Compare decimals

Compare $2.2$ and $2.09$. In the tenths place, $2>0$. So $2.2>2.09$.

Problem 10:

Step1: Calculate the right - hand side

Calculate $8+\frac{1}{5}+\frac{10}{100}$. $\frac{1}{5}=0.2$, $\frac{10}{100} = 0.1$. Then $8 + 0.2+0.1=8.3
eq8.15$.

Answer:

1. False; 8. True; 9. True; 10. False
