1. Tommy and Robbie share 48 marbles between them in the ratio 5 How many

aleksley [76]

Answer:

The number of marbles does Tommy will get is 18 .

Step-by-step explanation:

Given as :

The total number of marbles share between Tommy and Robbie = 48

The marbles were distributed between then in the ratio 3 : 5

Let the number of marbles does Tommy have = 3 x

The number of marbles does Robbie have = 5 x

Now,

According to question

The total number of marbles share between Tommy and Robbie = 48

Or, the number of marbles does Tommy have + The number of marbles does Robbie have = 48

Or, 3 x + 5 x = 48

Or, 8 x = 48

∴ x = $\frac{48}{8}$

I.e x = 6

So, the number of marbles does Tommy have = 3 × 6 =18

The number of marbles does Robbie have = 5 × 6 = 30

Hence the number of marbles does Tommy will get is 18 . Answer
