Lauren brings brownies to class one day. she gives 3/5 of them to her friends gareth, tammy, and camilla. if she gave them 21 brownies, how many did she bring to class?

If 3/5 of all the brownies is 21, then 5/3 of 21 is the number of the brownies that Lauren brought in.

That probably sounded super confusing. When multiplying a number by a reciprocal of a fraction (a fraction where the numerator and denominator is reversed), the previous fraction multiplication is reversed.

Multiplying 21 with 5/3 will give us the original number of brownies.

Lauren originally brought 35 brownies.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
