Distributive property of Multiplication with respect to addition
a × (b+c)=a×b+a×c
Number of situps done by marla in a day=65 sit ups
Number of situps done by Marla in a week
=65 × 7
=7 × 65------Using Commutativity(A×B=B×A)
=7 × (60 +5)----Using Distributivity of Multiplication with respect to Addition
=7 ×60 +7 ×5
=420 +35
=455 sit ups
