First, you have to divide 10 by 3, which is 3.333... or 3.3. Now you have to multiply that by $6.90. $6.90 x 3.3=22.77. 22.77 rounded to the nearest tenth is 23, so 23 would be your answer. It can aslo be shown as $3 over $6.90, and 10 over <em>x. </em>
Each is 7 long and the whole piece is 56 so we can make 8 down the length and each is 1 wide and the whole things is 3 so that makes 3 across. we multiply these to get 8*3= 24
