if it is a grid out of 100, which it usually is, change the decimals to a fraction ex: 1.4=140/100.
Draw a 10x10 grid and shade in 57 of the cells in the grid.
9.5% of 78With decimals:= 78*.095= 7.41With fractions:95/1000 = x/78Cross multiply7410 = 1000xDivide both sides by 1000x = 7.41
095 is an integer and so is already rounded to a hundredth (and more). So te answer is plant 095 or plant 95.
You could make each box on the grid be 0.1 wide and 0.1 tall. Then shade over 7 boxes to the left and 4 boxes up. Then when you count the boxes you will have the answer, which will be 28 boxes, which are 0.1 by 0.1, so 0.7*0.4=0.28.

It would be a full grid(100 all shaded) and six more on another hundred-grid.
Draw a 10x10 grid and shade in 57 of the cells in the grid.
You will have to go into decimals.
That depends upon how many grid squares you have in total and the largest value you have to represent. Wherever possible, you should arrange that each square that you have to shade represents either a divisor or a simple fraction of all the values you have to represent. With 0.49 ml as one of the values, it is unlikely that the values you will have to represent are all multiples of 0.49 ml; nor are they all likely to be multiples of 0.07 ml. So unless you use 1 grid square to represent 0.01 ml you are going to have to shade a fraction of a grid square. Once you have chosen how much each grid square will represent, or have been given the value to use, divide the 0.49 by this value to find out how many grid square to shade: If each grid square represents 0.01 ml, shade 0.49 ÷ 0.01 = 49 of them If each grid square represents 0.02 ml, shade 0.49 ÷ 0.02 = 24 1/2 of them If each grid square represents 0.04 ml, shade 0.49 ÷ 0.04 = 12 1/4 of them If each grid square represents 0.05 ml, shade 0.49 ÷ 0.05 = 9 4/5 of them If each grid square represents 0.10 ml, shade 0.49 ÷ 0.10 = 4 9/10 of them etc.
You can use decimal models to add decimals by using the hundedths blocks as used in base-ten blocks and add the following decimals you need to and use the hundredths block to shade in the total.

0.095 is ninety five thousandths.
095 is an integer and so is already rounded to a hundredth (and more). So te answer is plant 095 or plant 95.

To model 1.04 on a grid, you can represent it as a square with side lengths of 1 and 0.04 units. This can be visualized as a square divided into 100 smaller squares, with 4 of those smaller squares shaded to represent the 0.04 part. Each smaller square would represent 0.01. This grid model can help demonstrate the concept of decimals and their relationship to whole numbers.
