(grade 9 academic math) last night your sister made cake for dessert. she cut the cake into 15 equal slices but only 13 slices were eaten. the next day, you ate 1/5 of the remaining cake for a snack. what fraction of the cake was left?

Step-by-step explanation:

If the cake was initially cut into 15 equal slices and 13 of those were eaten:

slices would be left

Since you only had 2/15 left and ate 2/75, we can subtract these amounts to find the remaining amount of cake.  However, fractions can only be subtracted if they have the same denominator:

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
