Answer:

$12.1 \div 0.11 \\ \frac{121}{10} \div \frac{11}{100} \\ \frac{121}{10} \ \times \frac{100}{11} \\ 11 \times 10 \\ 110$

Answer: 110

Turn each decimal into a Fraction

12.1 = 12 1/10

0.11 = 11/100

Turn 12 1/10 into an Improper Fraction

Multiply 12×10 and get 120. Now add 1 and get 121.

12 1/10 = 121/10

Do Keep Change Flip:

Keep: 121/10

Change: ÷ into ×

Flip: 11/100 into 100/11

New Problem: 121/10×100/11

Multiply

121/10×100/11=12100/110

Divide

12100÷110=110

Find the least common denominator for these two rational expressions 7/n^2 -8/7n

lianna [129]

Answer:

7n²

Step-by-step explanation:

7/n² - 8/7n

Least common multiple will be the least common denominator

L.C.M = 7n²

Dividing the L.C.M by denominators and multiplying with numerators;

((7×7) - (n×8))/7n²

= (49 - 8n)/7n²

7n² is the least common denominator

olga55 [171]

Answer:

$P(\text{Pizza}\ |\ \text{Female})=0.225$

Step-by-step explanation:

The two-way frequency table is attached below.

We have to calculate the probability of, a person chosen at random prefers pizza given that they are female, i.e $P(\text{Pizza}\ |\ \text{female})$

This is a conditional probability.

We know that,

$P(A\ |\ B)=\dfrac{P(A\ \cap\ B)}{P(B)}$

So,

$P(\text{Pizza}\ |\ \text{Female})=\dfrac{P(\text{Pizza}\ \cap\ \text{Female)}}{P({\text{Female}})}$

From the table,

$P(\text{Pizza}\ \cap\ \text{Female)}=\dfrac{119}{1000}$

$P({\text{Female}})=\dfrac{530}{1000}$

Putting the values,

$P(\text{Pizza}\ |\ \text{Female})=\dfrac{P(\text{Pizza}\ \cap\ \text{Female)}}{P({\text{Female}})}=\dfrac{\frac{119}{1000}}{\frac{530}{1000}}=0.225$

eduard

Answer:

Candice ran 1/6 of a lap further than Chris.

Step-by-step explanation:

we know that

To find out how much further Candice runs than Chris, subtract the distance Chris runs from the distance Candice runs

$\frac{1}{2}-\frac{1}{3}=\frac{3-2}{6}=\frac{1}{6}\ lap$

therefore

Candice ran 1/6 of a lap further than Chris.
