This is a proportion problem involving cross multiplication.

=

Now first multiply 340 x 4 which equals 1,360
Now divide that number by 60 to get your X value
Answer is 22.67 minutes or 23 if it needs to be rounded (that depends on your teacher).
Area = pi * radius^2
radius = diameter/2 = 26/2 = 13 feet
Area = 3.14 * (13^2)
Area = 3.14 * 169 = 530.66 ft^2
I think the best approach is assuming in percentage. if the cake= 100, then just add the 47 and 23. that would equal 70. then, subtract the 70 from the 100. that would be 30 as your final answer.
« 47+23+?=100 »
« 70+?=100 »
-70 -70
?=30
