Multiplying fraction (2 1/2)(3 1/5)=
eduard
First you make the fractions top heavy instead of mixed numbers, so:
5/2 × 16/5
Then you just multiply across:
5 × 16 = 80
2 × 5 = 10
Your answer is 80/10, which can be simplified to 8.

(HELP ASAP!)<br>Which postulate or theorem proves △HJZ∼△WJR ?
Tomtit [17]

Answer:

SAS Similarity Theorem

Step-by-step explanation:

we know that

<u>SAS Similarity Theorem</u>: States that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar

In this problem

∠HJZ=∠RJW ----> by vertical angles

and

WJ/HJ=JR/JZ

substitute the values

8/4=6/3

2=2 ----> is true

so

Two sides of triangle HJZ are proportional with the two corresponding sides of triangle WJR and the included angle is congruent

therefore

Triangles are similar by SAS Similarity Theorem
