Is 9/10, 1 1/5, 1 1/2 a right triangle?

tankabanditka [31]

Answer:

using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2

a²+b²=c²

(9/10)²+(11/5)²=(11/2)²

81/100+121/25=121/4

lcm of 25 and 100 =100

(81+484)/100=121/4

565/100=121/4

113/20=121/4

since they are not equal therefore it's not a right angle triangle

Whats 2 1/2 X 1 1/2 someone pls help

Wittaler [7]

Answer:

15/4

Step-by-step explanation:

2 1/2 x 1 1/2

First, make them both improper fractions to make them easier to multiply

5/2 x 3/2

Multiply their numerators together to get the numerator and multiply their denominators together to get the denominator.

5 x 3 = 15

2 x 2 = 4

5/2 x 3/2 = 15/4

Help? I forgot how to do this lol I have really bad memory

$\dfrac{2}{3} \times \dfrac{3}{4} \times \dfrac{1}{2}$

Cancel out 2, the common factor for the numerator and denominator:

$= \dfrac{1}{3} \times \dfrac{3}{4} \times \dfrac{1}{1}$

Cancel out 3, the common factor for the numerator and denominator:

$= \dfrac{1}{1} \times \dfrac{1}{4} \times \dfrac{1}{1}$

Combine into single fraction:

$= \dfrac{1 \times 1 \times 1}{1 \times 4 \times 1 } = \dfrac{1}{4}$

$\bf \text {Answer = } \dfrac{1}{4}$
