Step-by-step explanation:
In order to find the total amount of Diana's clothes that are black or white, you need to add the fractional amount of clothes that are white (1/6) and the fractional amount that are black (7/12). But, when you add fractions they need to have the same denominator, so you need to find the least common multiple of both denominators, in this case '12':
So, 
Now, simplify: 
22/7 is bigger than (pi).
But it's only about 0.04 percent bigger, so it's a great number
to use in place of (pi), without too much inaccuracy at all.
Longest Side is 15 and 21.
Find the ratio which is 21/15.
= 1.4 , so every side multiply by 1.4 will give the size of the sides of the other triangle.
*note : it's a similar triangular so enlargement is used and the enlargement factor (k) is = 1.4*
so. 6 × 1.4 = 8.4
and. 8 × 1.4 = 11.2.
