To find the number we do the inverse of division, and that's multiplication. We multiply 8 x 5 x 3 to get 120, that's our number. So Fernando is thinking of the number 120, and we can prove that it's correct by dividing 120 / 3 then the result divide it by 5 and we get 8.

Simple, if you have the ending number as 8;

You divided it by 5. So go in reverse, and multiply by 5.

8*5=40

Then, do the same thing again, you divided it by 3, so multiply by 3.

40*3=120.

Thus, the number that Fernando gave to Maria is 120.

2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?
Talja [164]

Answer:

There are 171 members in the club

Number of boys = 38

Number of girls = 133

Step-by-step explanation:

Let

x = total members of the club

Boys = 2/9x

if there are 95 more girls than boys

Girls = 2/9x + 95

how many girls are there in club?

Total members in the club = boys + girls

x = 2/9x + 2/9x + 95

x = 2+2/9x + 95

x = 4/9x + 95

x - 4/9x = 95

9x-4x/9 = 95

5/9x = 95

Divide both sides by 5/9

x = 95 ÷ 5/9

= 95 × 9/5

= 855/5

= 171

boys = 2/9x

= 2/9 * 171

= 342 / 9

= 38

Girls = 2/9x + 95

= 38 + 95

= 133

Total = 38 + 133

= 171

There are 171 members in the club

Number of boys = 38

Number of girls = 133
