Emma bought 3.5 kg of apples and 2.75 kg of oranges. She also bought 1.2 kg of bananas but used 0.65 kg for a smoothie. If the total weight of the fruits is divided equally into 4 bags, how much fruit is in each bag?
Step 1: Add the total weight of all fruits
3.5+2.75+1.2=7.45
Step 2: Subtract the amount used for the smoothie
7.45−0.65=6.80
Step 3: Divide the remaining weight into 4 bags
6.80÷4=1.70
