Step-by-step explanation:
so, that means the friend's garden length is
15m 24cm + 2m 98cm
we can do this in 2 main ways.
1. using the fact that this is a metric system with 1m = 100cm.
15.24m + 2.98m = 18.22m = 18m 22cm
2. using fractions
15 24/100 m + 2 98/100 m =
= (1500 + 24)/100 + (200 + 98)/100 =
= 1524/100 + 298/100 = (1524 + 298)/100 =
= 1822/100 = (1800 + 22)/100 = 18 22/100 m =
= 18m 22cm
ultimately, they are both really using the same principles, but it looks a little bit different.
