Answer:
<em>Neha and Daniel do not use the same ratio of bananas to oranges</em>
<em>Neha used the grater ratio of bananas to oranges</em>
Step-by-step explanation:
<u>Ratios</u>
The ratio is expressed as a:b, where a and b are whole numbers.
Neha used 4 bananas and 5 oranges in her fruit salad. Daniel used 7 bananas and 9 oranges in his.
We use cross multiplication to find if the ratios of bananas to oranges are the same.
Neha s ratio is 4:5
Daniel s ratio is 7:9
To compare both ratios we use the expression:
The question mark means equality could be true or false.
The cross multiplication consists of multiplying the denominator of one side by the numerator of the other side:
Operating:
The equality is false, thus
Neha and Daniel do not use the same ratio of bananas to oranges
Since the left side of the equality is greater than the second:
Neha used the grater ratio of bananas to oranges
