Question 830248
You are looking for a three-part ratio, Grade4:Grade5:Grade6.


Currently you know this:  
4:5:{48%_of_Grade5}

= 4:5:0.48*5

= 4:5:2.4


Ratios are best written with natural numbers, so considering the denominator of 2.4 would be 5, try multiplying the three parts of the ratio by 5:
4*5=20; 5*5=25; 2.4*5=12.


You could show this ratio as 20:25:12

Note:
{{{2.4=2&4/10=2&2/5}}}, the denominator is 5.
