today in our second period of math, Mr. H showed us how to solve percent problems using the grids. he also gave us a work to do about percent problems.we need to solve the ff. problems which is our assignment for tomorrow.
1.what is 45% of 60?
2.what is 21%of 78?
3.what is 35% of 18?
4.what is 91% of 210?
5.what is 55% of 310?
6.what is 12% of 125?
7.what is 70% of 256?
In able to answer these following question, the first thing we need to do is find the equivalent of the tiny square inside the whole square.You need to divide the whole square to 100 to get the equivalent of the tiny square.
after you divide it, you multiply it to the percent number that was given.
after you completed computing the percent problem, you must show it in grid.
