Hannah had some tants 1/5 of the tarts were pineapple tarts and the rest were coconut tarts She gave 1/2 of the coconut tarts to her uncle and she had 18 coconut tarts left. What was the total number of pineapple and coconut tarts Hannah had at first?

Total tarts = 45

Step-by-step explanation:

Let x be the total tarts

Pineapple tarts = 1/5

So, coconut tarts are 4/5

She gave 1/2 of the coconut tarts to her uncle,

1/2 * 4/5 = 4/10 = 2/5

So, to find x

4/5x - 2/5x = 18

2/5x = 18

2x = 18 x 5

x = 90/2

x = 45

x = 12

y = 1

for the points!
