Answer:
Step-by-step explanation:
n - smaller number
The larger number is 12 times the smaller number
12n - larger number
n + 12n = 13n - the sum of these numbers
13n = 15600
÷13 ÷13
n = 1200
12n = 12•1200 = 14400
Check: 14400+1200 = 15600
0
The five smallest prime numbers are 2, 3, 5, 7 and 11.
2 × 3 × 5 × 7 × 11
= 2310
Divide by 42.
2310/42
= 55, Remainder 0
yea
1440
Explanation:
1200 × .05 = 60
60 × 4 = 240
1200 + 240 = 1440
X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2
X + (2 and 1/2) - 3/4 = 5 and 1/4
X + 2 and 2/4 - 3/4 = 5 and 1/4 <--- common denominator
X + 10/4 - 3/4 = 21/4
X + 7/4 = 21/4
