A farmer plants corn in 1/4 of his field. He plants white corn in 3/5 of the corn
section of his field. This situation is shown in the model. What fraction of the
whole field is planted with white corn?

Step-by-step explanation:

Fraction of the total that is for corn (TC - Total corn):

fraction of the corn section that is for white corn (WC - white corn in the corn seccion):

we need to find the fraction of the whole field that is for the white corn.

For this we need to find how much is out of the destinated to corn, and this will be the fraction of the total that is for white corn. We find this fraction by multiplying the fraction of corn () by the fraction of white corn in the corn section ().

I will call the total fraction of white corn TWC, thus:

the answer is: of the whole field is planted with white corn

there are no figures how am i supposed to answer this question

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
