Answer: \frac{4}{5}

Step-by-step explanation: The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(\frac{10}{100}, \frac{7}{10}) = 100

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(\frac{10}{100}×\frac{1}{1})+(\frac{7}{10}×\frac{10}{10})=?

Complete the multiplication and the equation becomes

\frac{10}{100}+\frac{7}{10}=?

The two fractions now have like denominators so you can add the numerators.

Then:

\frac{10+70}{100}=\frac{80}{100}

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 80 and 100 using

GCF(80,100) = 20

\frac{80÷20}{100÷20}=\frac{4}{5}

Therefore:

\frac{10}{100}+\frac{7}{10}=\frac{4}{5}

Answer:

The smaller number is: 8

The bigger number is: 20

Step-by-step explanation:

Ok let's say the two numbers are x and y.

x is the smaller one, and y is the bigger one.

This is the equation to find x:

x + 4y = 88

x + y = 28

x - x + 4y - y = 88 - 28

3y = 60

y = 20

x + 20 = 28

x = 8

Part A: If (72)x = 1, what is the value of x? Explain your answer. (5 points)
vichka [17]

Answer:

see below

Step-by-step explanation:

Part A:  (72)^x = 1

Take the log base 72 of each side

log72(72^x) = log 72(1)

We know log a^b = b log a

x log72(72) = log72(1)

x =  log72(1)

x = 0

Part A:  (70)^x = 1

Take the log base 70 of each side

log70(70^x) = log70(1)

We know log a^b = b log a

x log70(70) = log70(1)

x =  log70(1)

x = 0
