common denominator = 80        

3/80 and 24/30

Step-by-step explanation:

Same thing as last one, you multiply the denominators of each fraction together. 8x10=80 then multiply the fraction with the opposite denominator, 3x10=30 so 3/80 and 3x8=24 so 24/30.

common denominator: 40

3/8 = 15/40

3/10 = 12/40

Step-by-step explanation:

8 x 5 = 40 and 10 × 4 = 40. This means 40 is the common denominator.

To get from 8 to 40 you multiply by 5 and so you multiply 3 by 5. This means the numerator is 15.

To get from 10 to 40 you multiply by 4 and so you multiply 3 by 4. This means the numerator is 12.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
