To find out the answer or the product E
xample;0.1x0.1=0.01
the area
You multiply numbers because you're trying to find a multiple. You multiply prime numbers because you're trying to find the smallest common number. You could multiply common composite factors, but the result wouldn't necessarily be least.
No because you multiply the dimensions
You add first and then divide
15% is 0.15 so all you have to do is multiply 0.15 by whatever number your trying to find 15% of.
It depends what you are trying to get the area of. For example, to find the area of a square or rectangle you multiply the length times the width. But to find the area of a triangle, you multiply the height times 1/2 of the base. So yes, you usually multiply to find area of a figure, but there may be more steps to the process.
That is necessary if trying to find an equivalent ratio: not otherwise.
Yes, the area of an object is most commonly width times length.
77,625 lbs. you multiply the size of the excavator by 225 when you are trying to find the weight of them in pounds
Multiply. Be careful what you multiply because different shapes have different rules. Squares are different than triangles, are different than circles, etc. Adding gives you a perimeter.
It depends on the shape of the area you are trying to find. The most basic calculation would be the area of a rectangle, which is A = lw (area = length times width).
its depends on what you are trying to do with the 3 and 5.. are you trying to multiply it or Add what are you trying to say?
