Step-by-step explanation:

total cakes=  30

  • 30*1/5= 6 cakes

Gave to Jane

  • 30*1/10= 3 cakes

Cakes left:

  • 30- (6-3)=21

  • 21/30= 7/10 or 70 %

Answer:

7/10

Step-by-step explanation:

Cakes Simon gave to Sali = 30*1/5

= 6

Cakes Simon Gave to Jane = 30 * 1/10

= 3

Cakes left = 30 - (6-3)

= 21

21 cakes were left, so in terms of a fraction, it'd be 21/30, which can be reduced to 7/10

Hope this helps!
