M = 57+46
(Since she has 46 less then martha, you know to find how many martha has you have to add 46!)
M=103
So martha has 103 coins!
Subtract 50 from both sides:
hope this helps!
Mean
add up numbers and divide by how many there are
(1+1+5+3+6+6)/7=3 and 2/3
Find the number that both can be divided by i.e. the common denominator of 56/8 is 8 because 56 is divisible by 8 and 8 is also divisible by 8.
so by finding the common denominator and dividing the fraction, the equation would look like this: 7/1
If you mean turn 25/8 into a decimal its 3.125 but if u need it in a mixed fraction its 3 1/8
