To find the cost of 700g at 90p per kg, we first need to convert 700g to kg. There are 1000g in 1kg, so 700g is equal to 0.7kg. Next, we calculate the cost by multiplying the weight in kg (0.7kg) by the cost per kg (90p): 0.7kg * 90p = 63p. Therefore, the cost of 700g at 90p per kg would be 63p.
700g would be 63p
The answer is 0.63p (90p/1000g=0.0009p per g x700g=63p)
