Is Raj correct? Raj is making korma for a party. He puts 25 g of curry
powder on a food scale. The food scale has marks every
0.1g. To measure for each recipe, Raj removes į g of
curry powder from the scale 7 times. He says the mass of
the remaining curry powder is between 18.2 g and 18.3 g.
No, because 7 x
= 7; and 25 – 7 = 17.75, which is between 17.7g and 17.8 9.
O No, because 7 x 1 and 25 – 7 = 23.25, which is between 23.2 g and 23.3 g.
o Yes, because 7 x 1 = 7; and 25 – 71 = 18.25, which is between 18.2 g and 18.3 g.
O Yes, because 7 X
and 25
= 18.25, which is between 18.2 g and 18.3 g.​
