To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get:
Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:
That's the sum of 1/3 + 4/5.
Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:
In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:
Since 119 and 15 don't have a common factor, so they can't be simplified.
So, the answer is 119/15.
Hope this Helps! :D
What you have to do first is to add and
,
Further Explanation
Therefore we have:
= +
= ( +
) / 15 (15 is the smallest number that divide both denominator also known as LCD)
= (5 x 1) + (3 x 4) / 15
= 5 + 12 / 15
=
Therefore, the sum of +
is
But since the question says you should determine the sum of the 2 fractions, therefore you should multiply by 7. Therefore you should have:
X 7 (7 can also be expressed as
)
= x
(notably, in multiplication there is no need for the fraction to have the same denominator. You can multiply both numbers at the top together (numerator) and do same with the denominator.
=
=
Therefore, 7 times as much as the sum of and
is

To be a rectangle it must have 4 right angles and 2 pairs of parallel sides
A rhombus has 2 pairs of parallel sides so it is a parallelogram, but does not have to have 90 degree angles. (Rhombuses with 90 degree angles are squares)
