Answer 2

Answer:

a) 24

b) 7200 seconds

c) -3763

d) 2008m

e)406

f) 773

g) 8

h) 7 weeks

Step-by-step explanation:

a) 7 sets of 8 = $7*8=56$

   8 tens = $8*10=80$

Difference = $80-56=24$

b) 2 hours = $60*2$ minutes = $120$ minutes

                 = $120*60$ seconds = $7200$ seconds

c) 37,80 less than 17

   $17-3780 = -3763$

d) 2km 8m = $2000 m+8m = 2008m$

e) $O +239=645$

   $O=645-239=406$

f) $427+346 = O$

  $O = 773$

g) $105-97 = 8$

h) 49 days = ? weeks

1 week = 7 days

49 days = $\frac{49}{7}$ weeks

49 days = 7 weeks
