The correct option of your question is D
Step-by-step explanation:
To solve the sum we need to understand the distributive property
a×(b+c) = a×b + a×c
Here,
Option D is given as
RHS = 5(3+8) [ a=5, b=3 and c=8]
=15 + 40
= LHS
It satisfies the distributive property.
You can cross check the property with the other options.
D is the correct option.
We know that 1 feet is 0.3m and that 1 inch = 0.0254 m
To get the result we have to multiply 5 feet by 0.3 and 2 inches by 0.0254 and add it.
5*0.3=1.5
2*0.0254=0.0508
Now adding
1.5+0.058=1.55m - its the answer
The 7 in 506,087 is in the ones place.
Rember a variable without a coefficient or number is 1 so 1×2+3 1×2=2 2+3=5
