Thursday’s Maths: Equations
I am learning to use addition and subtraction to work out fractions of a set.
I have a 25cm chocolate log cake left and i have to share it with 5 of my friends so i have to think of a way to solve it so if i have a 25 cm log and we divide it by 5 we would give each person 1 cm of log cake until there is nothing left.
If we count in 5s, we start off from 5 x 1 and continue until we count up to 25.
So 5 x 1 = 5, 5 x 2 = 10, 5 x 3 = 15, 5 x 4 = 20, 5 x 5 = 25 which means each of my friends get 5 cm each.
25cm divided by 5 = 5.
