Question

Evaluate : 2^3/2^5 × 3^5/3^3​

Answer 1

2/3 + 3/5 = 19/

2/3 + 3/5 = 19/15

2/3 + 3/5 = 19/15 = 1 4/

2/3 + 3/5 = 19/15 = 1 4/15

2/3 + 3/5 = 19/15 = 1 4/15 ≅ 1.2666667

2/3 + 3/5 = 19/15 = 1 4/15 ≅ 1.2666667Spelled result in words is nineteen fifteenths (or one and four fifteenths).

Answer 2

Step-by-step explanation:

Evaluate 2/3 + -4/5 + 1/3 + 2/5

We have to evaluate 2/3 + 1/3 + -4/5 + 2/5

Solution

Firstly group the rational numbers with same denominators

2/3 + 1/3 + -4/5 + 2/5

(2+1)/3 + (-4+2)/5

3/3 + -2/5

1/1 + -2/5

By taking LCM for 1 and 5 we get, 5

(1×5)/(1×5) + (-2×1)/(5×1)

5/5 + -2/5

Since the denominators are same can be added directly

(5-2)/5 = 3/5

Answer

2/3 + 1/3 + -4/5 + 2/5= 3/5
