Question

There are 86 calories in 100 g of banana

There are 89 calories in 100 g of yogurt
Amanda has 70 g of banana and 140 g of yogurt for breakfast
Work out the total number of calories in this breakfast

Answer 1

184.8 calories :)

the grams are both 100, meaning we can use percentages. banana: 70% of 86 (.7*86=?) is 60.2 calories. yogurt: 140% of 89 (1.4*89=?) is 124.6 calories. 60.2+124.6=184.8 calories
