Studdy Solution

STEP 1

What is this asking? We need to multiply two fractions and simplify the result to the lowest terms. Watch out! Don't forget to simplify the fraction after multiplying!

STEP 2

1. Multiply the numerators.
2. Multiply the denominators.
3. Simplify the resulting fraction.

STEP 3

Let's **multiply** the **numerators** of the two fractions!
We have 77 and 1010, and 710=707 \cdot 10 = 70.
So, our new **numerator** is **70**.
Easy peasy!

STEP 4

Now, let's **multiply** the **denominators**, 88 and 33.
We get 83=248 \cdot 3 = 24.
So, our new **denominator** is **24**.
Awesome!

STEP 5

We currently have the fraction 7024\frac{70}{24}.
We need to **simplify** this.
Both the numerator and denominator are even, so they're both divisible by 22.
Let's **divide** both by 22.

STEP 6

Dividing 7070 by 22 gives us 70÷2=3570 \div 2 = 35.
Dividing 2424 by 22 gives us 24÷2=1224 \div 2 = 12.
So, our **simplified** fraction is now 3512\frac{35}{12}.

STEP 7

Can we simplify 3512\frac{35}{12} further?
Let's see!
The factors of 3535 are 1,5,7,1, 5, 7, and 3535.
The factors of 1212 are 1,2,3,4,6,1, 2, 3, 4, 6, and 1212.
The only **common factor** is 11, which means the fraction is already in its **simplest form**!

STEP 8

Our final answer, the product of 78\frac{7}{8} and 103\frac{10}{3} simplified to the lowest terms, is 3512\frac{35}{12}!
