28/42 ÷2
14/21 ÷2
2/3
28/42 in simplest form is = 2/3
Okay, so this is just a basic multiplication problem. first, we need to divide to figure out how much the trout population grows after 1 year. If it doubles in 4 years, then it will rise by a quarter each single year. So to put that in terms of fractions, then for every year, the equation would be 250x1/4. So then we do the equation, coming up with 62.5. This means that the population rises roughly 63 fish a year. So after 1 year, you will have roughly 313 fish. (312.5 to be exact). Then to get that by ten years, we can just multiply the number that we got for one year by ten. 62.5x10=625. So then we add the 250 original trout, and 250+625=875. So after 10 years, there will be 875 trout.
Personally I would take each ingredient/ 4, then subtract ur answer from the original. So 80g strawberry jelly, 6sponge fingers, 315 custard, 35 tinned fruit
We know that to angle A coresponding side a and to angle B corespond side b so there given that to angle A with measure of 30 degree corespond the side length of side a = 2 but from this given details that side b has length equal 2 so from this reasult that the measure of angle B is equal 30 degrees too same with angle A
