Final answer:
To find the weight of the red ant, set up a proportion using the given information and solve for x.
Step-by-step explanation:
To find the weight of the red ant, we can set up a proportion. We know that the ant can carry 1/10 of its weight, which is equal to 7/250 grams. So, we can set up the following equation:
(1/10) x = 7/250
To solve for x, we can cross-multiply:
250x = 7 * 10
Divide both sides by 250 to isolate x:
x = (7 * 10) / 250
Calculating the value of x gives us:
x = 0.28 grams
