Answer:
5.5
Step-by-step explanation:
4×3÷4+5×3÷5-1×1÷2
Lets add parentheses (where I think they belong).
4×(3÷4) + 5×(3÷5)-1×(1÷2)
PDMAS: Do the operations in the parentheses first.
4×(3÷4) + 5×(3÷5)-1×(1÷2)
4×(0.75) + 5×(0.6)-1×(0.5)
Now do Divions and the Multiplications.
4×(0.75) + 5×(0.6)-1×(0.5)
3 + 3 - 0.5
6 - 0.5
= 5.5
