contains 46 oranges.

How many buckets will 736 Oranges fill?

One bucket contains 46 oranges

(736 ÷46) bucket

(b) 110.7 ÷ 41

- Order of
operation (Use of BODMAS)

Use the following order for problems with Mixed operations

B = Brackets, O = Off

D = Division, M = Multiplication,

A = Addition, S = Subtraction

E.g. (a). 20 × 3 × 7

= 20 × 3 × 7 = 60 × 7 = 67
