The fraction of marbles in the box that is green = ⁷/₍₅₊₇₊₈₎
                                                                               
                                                                                =  ⁷/₂₀

If there are 240 marbles in the box, then the number of green marbles = (240 × ⁷/₂₀) = 84 marbles

∴ 84 of the marbles in the bag are green.

B) Convert 101, into denary number​
Tamiku [17]

If 101 is given in base <em>b</em>, then in base 10 you have

101_b = 1\times b^2 + 0\times b^1 + 1\times b^0 = b^2 + 1

For instance, if <em>b</em> = 2, then

101₂ = 2² + 1 = 5₁₀

If <em>b</em> = 3, then

101₃ = 3² + 1 = 9₁₀

If <em>b</em> = 4, then

101₄ = 4² + 1 = 17₁₀

The answer depends entirely on the base of the given number.
