Answer 1

Answer:

13) a]2

b]297/70

c] ?

d]2713

e]132

f]119934448

g]7220

14) -31/45, -32/45, -33/45, -34/45

15) not able to draw here

16) 78

Step-by-step explanation:

13. Evaluate:

a) (2)=2

b)(81) * x 3° =>81*(11/210) =>297/70=>4.243

..... convert degree to radian and then in number

C)[3* + 3*j* ........ what is *j here.

d) 2713 =2713

e)23 X6-2=>(23*6)-6=>138-2=>132

f)23 x3134 x32x52 =>119944448

g)62 x 120=>7220

14. Find four rational numbers between - 2/3 and -4/5.

Ans=> step 1. Make denominator same

so... multiple -2/3 by 5/5

and... multiple -4/5 by 3/3

then... ve get -10/15 and -12/15

step 2. multiple both by that number by which

you got your ans. {here by 3/3

we get... -30/45 and -36/45

so our rational numbers between - 2/3 and -4/5 are :

-31/45, -32/45, -33/45, -34/45

15. Represent - 9/8 on a number line.

0 |----------|----------|2

1(8/8)

16. Simplify: 6 + 9x8+ => 6+(9†8)=> 6+72=>78
