To find the heaviest mass of potatoes Nombulelo can add to her bag, we need to subtract the total mass of the items she has already from the maximum mass she can carry.
The total mass of the items she already has is 450g + 0.25kg + 650g + 1.3kg (since 1kg = 1000g)
= 450g + 250g + 650g + 1300g
= 2650g
Converting 4kg to grams, we have:
4kg = 4 * 1000g = 4000g
Now we can find the heaviest mass of potatoes she can add by subtracting the total mass she already has from the maximum she can carry:
Heaviest mass of potatoes = 4000g - 2650g
= 1350g
Therefore, Nombulelo can add potatoes with a maximum mass of 1350g to her bag.
The masses of the items in Nombulelos shopping are 450g,0,25kg,650g and 1,3g.The doctor said that she must not carry more than 4kg.She still needs some potatoes.What is the heaviest mass of potatoes she can add to her bag?
