What is the value of the tape diagram if the ratio is 8 to 7 and the total is 195

If the ratio is 8:7, there are 8 + 7 = 15 kind of "parts" of the ratio. We know that the total value is 195, so we can calculate what value such one "part" represents:

195 / 15 = 13

So one "part" of the ratio is 13. Now if the ratio is 8:7, then the 8 is for 8 * 13 = 104 out of the total and the 7 is for 7 * 13 = 91 out of the total.

Doublecheck:

104 + 91 = 195, so it's correct :)

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
