Question

Sabin bought a cake. He ate 1/2 of it in the morning and 2/5 in the afternoon.How much cake did he eat altogether?How much cake is remaining?​

Answer 1

Answer:

he eat 7/10 of the cake and 3/10 is remaini

Answer 2

Answer: 9/10 of the cake he have ate and 1/10 of the cake was left.

Step-by-step explanation:

cake that he ate in morning : 1/2

cake that he ate in after noon : 2/5

cake he ate in total : 1/2 + 2/5

To add them we have to make their denominater same and to make their denominater same we have to find thier LCM.

= the LCM of 2 and 5 = 10

so 1/2 = 1 x 5 / 2 x 5 = 5/10

2/5= 2 x 2 / 5 x 2 =4/10

so total cake ate =5/10 + 4/10

=9/10

so cake left = 10/10 - 9/10 =1/10
