It is 63p.
The answer is 0.63p (90p/1000g=0.0009p per g x700g=63p)
It is 72p.
a duck
0.7kg=700g 1kg=1000g and 0.1kg=100g therefore, 0.7kg=700g
700g is equal to 0.7 kilograms.
Its accualy 72
15p
7 kg and 7000 g
50 percent of 90p = 45p50% of 90p= 50% * 90p= 0.50 * 90p= 45p
2.3 kg = 2300 g (1kg = 1000g)So, 2300 g + 250g + 700g = 3250g or 3.25kg
1 kg = 1000g ⇒ 850g is 1000g - 850g = 150g less than 1kg ⇒ 700g is 1000g - 700g = 300g less than 1kg The rest are left as an exercise for the questioner.
