Hey please help me please 1. What operation would you perform to express a measure given in the first unit as a measure in the second unit?

a) metres to centimetres

b) metres to millimetres

c) kilograms to grams

d) litres to millilitres

2. Will each number be larger or smaller than the given number? Then fill in the blank.

larger smaller a) 3 m = cm

larger smaller b) 28 cm = mm

larger smaller c) 2.4 km = m

larger smaller d) 485 mm = cm

larger smaller e) 35 cm = m

larger smaller f) 2.4 m = km

larger smaller g) 2495 mm = m

1.

a) metres to centimetres :

multiply length by 100

b) metres to millimetres:

multiply length by 1000

c) kilograms to grams:

multiply the mass value by 1000

d) litres to millilitres :

multiply volume by 1000

2.

a) 3 m = 3× 100 = 300 cm

b) 28 cm = 28 × 10 = 280 mm

c) 2.4 km = 2.4 × 1000

= 24 × 10^-1 × 10^3

= 24 × 10^2 =2400 m

d) 485 mm =485 / 10

= 485 / 10 ^1

= 485 × 10 ^-1

= 48.5 cm

e) 35 cm = 35 / 100

= 35 /10^2

= 35 × 10 ^ -2

= 0.35 m

f) 2.4 m = 2.4 / 1000

= 24 × 10 ^-1 / 10^3

= 24 × 10^-1 × 10 ^-3

= 24 × 10 ^ -4

= 0.0024 km

g) 2495 mm = 2495 /1000

= 2495 /10^ 3

= 2495 × 10 ^-3

=2.495 m

b, i believe, but not sure.
