Does anyone know number 25 i’m stuck on that

divide the ratio be common factors. for example, 4.

168 : 56

42 : 14              divide by 7

6 : 2                 divide by 2

3: 1

The answer is three

90

Step-by-step explanation:

Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.

20 + 3(7 + 4) + 5 + 2(7+9)

20 + 3(11) + 5 + 2(16)

20 + 33 + 5 + 32

You can add those final four numbers in any order you want, to get a sum of 90.
