Question

simplify and Express the result as a rational number in its lowest form 2 upon 5 into 3 upon 4 + 1 upon 25 into 1 upon 2 minus 2 upon 10 into one upon 5.it is very urgent​

Answer 1

Step-by-step explanation:

Dividing the numerator and denominator of −924−924 by 3, we get

−924−924 = (−9)÷324÷3(−9)÷324÷3 = −38−38

Thus, the standard form of −924−924 is −38−38.

(ii) −14−35−14−35

The denominator of the rational number −14−35−14−35 is negative. So, we first make it positive.

Multiplying the numerator and denominator of −14−35−14−35 by -1 we get

−14−35−14−35 = (−14)×(−1)(−35)×(−1)(−14)×(−1)(−35)×(−1) = 14351435

The greatest common divisor of 14 and 35 is 7.

Dividing the numerator and denominator of 14351435 by 7, we get

14351435 = 14÷735÷714÷735÷7 = 2525

Hence, the standard form of a rational number −14−35−14−35  is 2

Answer 2

Answer:

x = (-23)+(22)+(-23)+(22)+.. .. .. .. 40 terms

Y = (11)+(-10)+(11)+(-10).. .. .. .. 20 terms

x = 20 pairs of (-23)+(22)= -1

There are 20 pairs so we will get - 1 [20 times]

So, x = - 1×20= -20

Y = 10 pairs of (11)+(-10) = 1

There are 10 pairs so we will get 1[10 times]

So, Y = 1 × 10 = 10

We have to find the value of:-

y - x = 10 - (-20)

= 10 + 20

= 30
