Question

plzz give me right answer ​

Answer 1

Answer:

1 i a) -198

ii b) -1

iii b)25/35

iv) a) 12 litre

v) b)1/100

vi b) 18 cm

vii c) 5.01

viii c) both

ix a) 1:30

x a) xy/100

2) -50+20-30+40 = -80+60 = -20

3) let 2 integer be x and y, x+y = -30 => 15 + y = -30

y = -30-15 = -45 therefore other integer is -45

4) 36×(-56)+(-56)×(-46)

-56( 36-46)

-56×-10

560

5) a) (-450)÷(3+6)

= -450÷9

= -50

b) [46×5×0]÷4

= 0÷4

= 0

6) 1½+3½+4

= 3/2+7/2+4

= 10/2 + 4

= 5 + 4 = 9

7)a) 1 day = 24 hours

5/6 of 24 hours = 5/6×24 = 20 hours

b) 1 hours = 60 minutes

2/3 of 60 minutes = 2/3×60 = 40 minutes

8) 50-29.425 = 20.575

therefore 29.425 is less than 50 by 20.575
