Can you show us what you have to tried so far? Is this part of your homework? The best way to go is to show us where you got stuck.

There are 99 melons and grapefruits in a crate. 23 grapefruits and melons are rotten. 8/9 of the melons and 3/4 of the grapefruits are not rotten. ow many rotten melons are there? How many rotten grapefruits are there?

Start with defining variables.
Let
the number of total grapefruits (rotten+good) = G
And
the number of total melons (rotten+good) = M
Then
the number of total in crate (rotten+good) = G+M
continue.....

Please show us what you have tried and exactly where you are stuck.

Let M be the number of melons and let G be the number of grapefruits.

"There are 99 melons and grapefruits in a crate."
So M+ G= 99.

"8/9 of the melons and 3/4 of the grapefruits are not rotten."
So 1/9 of the melons and 1/4 of the grapefruits are rotten.

"23 grapefruits and melons are rotten."
M/9+ G/4= 23.

"How many rotten grapefruits are there?

Solve the two equations M+ G= 99 and M/9+ G/4= 23 for G then find 1/4 of G.
