Rewrite 7/10 and 2/3 so they have a common denominator

7/10=21/30

2/3=20/30

7/10×3/3=21/30

2/3×10/10=20/30

3/3=1 and 10/10=1 therefore, you're simply renaming each fraction to its equivalent

Step-by-step explanation:

this implies that all possible options, except 24, can be accepted

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)
