More...

#1/4# = #2/8#. Okay so far?

So Emma can play for more than one minute. In fact, she can play for #(7/8)/(2/8) = 7/2 = 3.5# minutes.

GOOD LUCK

She can play for more than a minute

You would want to start by dividing her total credit by the credit required.
#(7/8)/(1/4)#

Convert it to multiplication by flipping the fraction
#(7/8)*(4/1)#

Simplify by removing the common 4
#(7/2)*(1/1)#

Multiply the two fractions
=#(7/2)#

#(7/2)# = #3(1/2)# which shows she can play for 3 and a #1/2# minute.
So yes, she can play for more than one minute.
