Answer 1

There are 17 letter blocks for every 3 number blocks, if you add them the sum between them is 20. How many times is it 20 on 140? It is 7 times. It means there are 7 times 17 letter blocks and 7 times 3 blocks

`\begin{gathered} 7\cdot17=119 \\ 7\cdot3=21 \end{gathered}`

There are 119 letter blocks and 21 number blocks
