The lowest common denomenator is the smallest common factor of them so
20=1 times 2 times 2 times 5
24=1 times 2 times 2 times 2 times 3
the lowest common denomenator is 1
I think the question should have been. what is the greatest common factor (4) or what is the smallest common multiple (120)
Convert 2.8 kilograms into 2800 grams.
Baby A weighs 2800 grams, baby B weighs 2950 grams -> The difference between the masses = 2950 - 2800 = 150 grams.
20% off
100-20=80
find 80% of 179
percent mean psarts ouf o 100
80%=80/100=0.8
'of' means mutipy
80% of 179=
0.8*179=143.2
saleprice=$143.20

Answer:
15 y 8
Step-by-step explanation:
y = x - 7
x² + y² = 289
sustituir: x² + (x - 7)² = 289
distribuir: x² + x² - 14x + 49 = 289
sustraer + simplificar: 2x² - 14x - 240 = 0
dividir: x² - 7x - 120 = 0
x² - 15x + 8x - 120 = 0
(x - 15)(x + 8) = 0
x = 15, x = -8 --> x ≠ -8 porque -8 no es naturales
sustituir: y = 15 - 7
simplificar: y = 8
