1.2 kilos of apples cost $3
How much do 2.5 kilos of apples cost ?
Use a proportion.
1.2/3 = 2.5/x
Cross multiply and solve for x.
To find out how much 2.5 kilos of apples cost, we can use the given information.
We know that 1.2 kilos of apples cost $3. To calculate the cost per kilo, we can divide the total cost by the weight:
Cost per kilo = Total cost / Total weight
In this case, the total cost is $3 and the total weight is 1.2 kilos. So, the cost per kilo of apples is:
Cost per kilo = $3 / 1.2 kilos = $2.50 per kilo
Now that we know the cost per kilo, we can multiply it by the weight of 2.5 kilos to find the total cost:
Total cost = Cost per kilo * Total weight
Total cost = $2.50 per kilo * 2.5 kilos = $6.25
Therefore, 2.5 kilos of apples would cost $6.25.
