Convert 200 cm to m.

  • 2 m
  • 20 m
  • 0.2 m

ProCompare and infer.

Bottle holds 2 litres. Sara pours 750 ml. How much left?

  • 1,250 ml
  • 750 ml
  • 2,000 ml
  • 1,000 ml

Answer: 1,250 ml. 2,000 − 750.

GuruMulti-step reasoning.

A jug holds 1 litre. Sara fills 4 cups, each 200 ml. Can she fill 5?

  • No - 5 needs 1,000 ml = exactly 1 l, OK so YES.
  • Yes always
  • No - too much
  • Cannot tell

Answer: No - 5 needs 1,000 ml = exactly 1 l, OK so YES.. 5 × 200 = 1,000 = jug.
